FLUSH GLOSETeTANK.

To all whom it may concern:

Be it known that I, JAMES A. EGAN, a

citizen of the United States, and a resident 'binations and features of construction hereinafter set forth'and claimed."

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views.

Figure 1 is a vertical sectional view, partly in elevation and partly broken away, of a flush closet tank embodying my invention.

Fig; 2 is a plan in'ew thereof, the top being removed.

Fig. 3 is a section on line A A, Fig. 2.

This flush closet tank comprises a tank or receptacle having an open uncontrolled outlet, a normally upright capsizable bucket located in the receptacle or tank, means antomatically controlling the filling of the bucket with water or other fluid, and manually operable means for controlling the capsizing of the bucket.

l designates the receptacle or tank which may be of any suitable form, size and construction, said receptacle or tank 1 having the open outlet pipe 2 in its bottom. The outlet pipe 2 extends above the bottom of the receptacle or tank 1, is open at its top,

and is formed with a small horizontally or laterally extending by-pass 3, below its top and located to drain ofi slowly, the water remaining in the receptacle or tank 1 below the level of the upper end of the pipe 2.

4 is the normally upright capsizable bucket located in the tank or receptacle 1, the bucket being here illustrated as having horizontal pivots ortrunnions 5 on opposite sides thereof which are arranged in suitable bearings 6 provided on opposite sides of the tank,

these bearings being preferably semi-circular so. that the-bucket can-be readily lifted out of the receptacle or tank and replaced therein. The bucket is normally arranged in upright positionand has a discharge portion arranged above and at one side of the axis of the bucket and located farther from said axis. in a radial line than the outline of Specification of Letters latent.

within the body of the bucket so'that the bucket isheld from upsetting by its contents and when aslight overturning impulse is given thereto, the water running through the outlet onto the discharge nozzle tends to upset the balance of the bucket.

The pivots 5 are so arranged relatively to the bucket 4: that the bucket 4 tends to return to its upright position and to remain in such position when filled. The empty bucket however, balances shortzof its upright position, as seen in Fig; 3, and is gradually returned to its upright position by the water filling-into the bucket. The filled bucket is stopped in its upright position by any suitable means, and, as here facilitate the action of the bucket, the bucket is formed with a rounding arcuate'wall'? on one side of the axis of its pivots 5 and with a flat side 8 on the opposite or discharge side of said axis, the rounding wall con- 'stituting onelateral side and the bottom of the bucket, and being concentric with the axis of the pivots 5, and the flat wall 8 extending inside or along'a chord of'the curve of the wall 7 if itwere continued, and the edge of the open top'also extending he plans within or'in a chord of the curve of the wall if extended: Hence, the bucket is cylindrical in part inthe' general form of a short cylinder, intersected by two planes which ineet. The ends or the sides from which thepivots or trunnions project are flat and are located close to the long sides of the tank or receptacle'l'; The bucket 4 is also formed with a baflie plate or partition -wall'9 partly closing a portion of the open top side of the bucket and extending from near thetop'inwardly toward the discharge wall 8, said wall 9 diverging from" the open top as it approaches the wall-8 and being formed with an outlet opening 10 adjacent to said side wall 8. The portion of the charge nozzle 11 arranged above and atone bucket in front ofthe wall 9 formsa disside of the axis of the bucket and farther I from the axis in a radial line'than the 'outline of ,the cylindrical partof the bucket.

ing out of the bucket and causes the same to run uniformly through the outlet 10 and normally confines thecontents of the bucket to substantially within the body or cylindrical part of the bucket whereby theb-ucket is held from upsetting by its contents. The free edge 9 of the wall 9 is located nearer the axis of the bucket than theend adjacent the wall 8, and this arrangement of the wall'9 together with the construction of the bucket causes the bucket ,to capsize. When the bucket is capsized, after the water in the nozzle has run out, the main body of the water will run out through the outlet 10 instead of over the top of the wall 9 and into the tank 1, and owing to the wall 9 and the shapeofthe bucket, the momentum of the bucket is nearly neutralized, and the mass of water on one side, that is, the outlet side of the axis of the bucket just overbalancestheweight of the water on the other side, as the bucket is capsizing. Hence, the water is not discharged from the bucket faster than it can-pass out through the, outlet 2. The capsizing movement oft-he bucket 4: is limited by the engagement of the upper edge of the wall ,7 with the inlet pipe.

The means for automatically controlling the filling of the bucket comprises a float 12 located in the bucket and carried by a lever arm 13 pivoted at 14 between its ends and connected to operating means 15 of the valve which controls the flow of water through theinlet pipe 16, the pivot 14 being located in a bracket 17 provided on the valve casing 18.

The inlet pipe 116 extends ventically into the tank or receptacle land has a laterally extending branch ,1-9 at its ,upper end extendin-g over the open top of the bucket 4 and the wall 9 in position to discharge thereinto in all positions of the bucket, this branch 19 leading vfrom the valve :18 which is located at the top of the pipe 16, The wall 9 is formed with a slot '20 for receiving the branch 19 during the capsizing of the bucket 4.

llromthe foregoing, it is obvious that the branch 19 of the inlet (pipe and the connections between the float 12 and the valve, extend into the bucket 4: through the opentop thereof.

The-manually operable means for controlling the capsizing of the bucket 4, in this embodiment of my invention operates-togive the initial starting movement to the bucket tocapsize the same, the arrangement of the pivot-s5 and of the body of the-bucket-being .such that the bucket when filled is but slightly overbalanced toward its upright p0- sit cn, and but slight movement overbalances the bucket toward its overturned position. Said means comprisesa rock shaft 21 journaled ,in the front-wall of the receptacle 4 or tank 1 and hearings-handle .22 a its oute 1,2ee,eeo

end, and a rock arm 23 at its inner end, which carries means as a roller 24 at its inner end, the roller riding upon the upper edge of one of the flat ends of the bucket and being movable into and out of detachable engagement with the bucket 1. I

In operation the bucket i is filled and the valve located the casing 18 is closed by the act-ion of the float 12. Upon the movement of the handle 22 to the left, Fig. 1, the rock arm 23 of the operatingmeans causes the roller 2i to move downwardly and to the left on the upper edge of the bucket,

and to tilt the bucket so thatithe centerof gravity is changed from the right side to the left side of a vertical line passing through the pivots 5, so that the weight of the water will complete the overturningof the bucket.

evenly and comes to an easy step at both ends of its HlOEQHIGHiZ, and further in that by the employment of the bucket the use of a llfilllJlQSOlllQVttlVB in the outlet isavoided- \Vhat I claim is: 1.
